So seemingly out of nowhere my car stopped boosting, my gauge reads that vacuum is where it should be and under acceleration I can see it coming out of vacuum but it only gets up to “0” or atmospheric pressure and stops no sound of turbo spool and no sound of diverter valve when gas is released which is normally very audible with my intake. Just pulled the diverter valve and everything looks fine on it. Any advise as to where to look next is appreciated

 

Neil,

Have a helper rev the engine while you carefully listen feel for the boost leak under the hood.
No check engine light?

 

No CEL, charge pipes seemed tight and can’t for sure hear or feel a vacuum leak but with having an aftermarket intercooler and having done the noise maker delete and turbo muffler delete I’m gonna just pull the hot and cold side pipes completely off and re clamp everything

 

Noise maker delete, on my list for after cool weather. Hot garage.

How did you do the block-off? Seal still intact?
